Sorry for hijacking, but I have the exact same issue. Your installation instruction is good, but does not solve the issue. The repository git://sw-stash.freescale.net/scm/dnind/sja1105-tool.git is still just as unavailable.

I guess the fsl-image-minimal configuration just does not contain the sja1105-tool. However, I am working with the SJA1105 switch on the LS1021ATSN board and I would like to build the sja1105-tool. So the question is: How can I get the source code of that tool?

I got a firmware image for the LS1021ATSN board from our distributor (EBV) that contains the sja1105-tool binary, but this version has some bugs. I would like to get the latest version of the tool with the bugs fixed or the source code to fix them by myself.
